The critical path includes the tasks by which the time of completion of the overall project (or the time by which the project completion will be delayed) is determined. It is necessary to manage these in a close manner so that timely project completion is ensured. The analysis of critical path can be regarded as the determination of the elements of the task that will be on likely or are on the critical path (the path that is longest through the network). It is a tool of project management that is used in a wide manner by which analysis of network is used to assist project managers to manage operations that are time-sensitive and complex.
